As the alarms sounded at the Louvre Museum on Sunday morning, four suspects took off on two motorbikes, winding their way through central Paris, allegedly carrying with them a haul of "priceless" jewelry once worn by queens and made of sapphire, diamonds and emeralds.

Paris' iconic Louvre Museum was forced to shut down on Sunday, October 19, after a group of chainsaw-wielding robbers made off with millions of dollars of priceless jewelry.

One object, the emerald-set imperial crown of Napoleon III’s wife, Empress Eugénie, containing more than 1,300 diamonds, was later found outside the museum, French authorities said.
